I. Container Startup Exception:

How to handle the exception library initialization failed - unable to allocate file descriptor table - out of memory during container startup?

(I) Cause

After installing Docker on different operating systems, the container runtime environments are inconsistent, requiring adjustments to Docker runtime parameters.

(II) Solution

• Edit the /etc/systemd/system/docker.service file. In some systems, the file is located at /lib/systemd/system/docker.service.

View the location of Docker's systemd (docker.service) configuration:

systemctl status docker

• Modify the following parameters:

LimitNOFILE=65535
LimitNPROC=65535
LimitCORE=65535

• Execute the following scripts:

systemctl daemon-reload
systemctl restart docker

II. Container Startup Exception II:

How to handle the exception library initialization failed - unable to allocate file descriptor table - out of memorypanic: signal: aborted (core dumped) during container startup?

(I) Problem Symptoms

1. The configuration based on [Issue 1] still does not take effect.
2. Attempts to modify the ulimits of the host system kernel and restart Docker still result in errors. Modify docker.service (file location: /etc/systemd/system/docker.service or /lib/systemd/system/docker.service in some systems).

(II) Solution

View the location of Docker's systemd (docker.service) configuration using the method in [Issue 1].

Add the default ulimit configuration for container creation after the ExecStart command, as follows, setting the container's ulimit to 65535:65535 when starting:

--default-ulimit nofile=65535:65535

After configuration:

ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --default-ulimit nofile=65535:65535

Execute the following scripts:

systemctl daemon-reload
systemctl restart docker

Troubleshooting process:

After troubleshooting, the cause was found to be a DNS configuration issue. Changing to an Alibaba Cloud IP resolved the problem.
